Atomic append on windows is only supported on local disk files, and it may
cause errors in other situations, e.g. network file system. If that is the
case, this config option should be used to turn atomic append off.

When switching branches with "git checkout -m", local modifications
can block the switch. Teach the -m flow to create a temporary stash
before switching and reapply it after. On success, only "Applied

kept and the user is told they can resolve and run "git stash drop",
or run "git reset --hard" and later "git stash pop" to recover their
changes.

Implement the built-in fsmonitor daemon for Linux using the inotify
API, bringing it to feature parity with the existing Windows and macOS
implementations.
The implementation uses inotify rather than fanotify because fanotify
requires either CAP_SYS_ADMIN or CAP_PERFMON capabilities, making it
unsuitable for an unprivileged user-space daemon. While inotify has
the limitation of requiring a separate watch on every directory (unlike
macOS's FSEvents, which can monitor an entire directory tree with a
single watch), it operates without elevated privileges and provides
the per-file event granularity needed for fsmonitor.
The listener uses inotify_init1(O_NONBLOCK) with a poll loop that
checks for events with a 50-millisecond timeout, keeping the inotify
queue well-drained to minimize the risk of overflows. Bidirectional
hashmaps map between watch descriptors and directory paths for efficient
event resolution. Directory renames are tracked using inotify's cookie
mechanism to correlate IN_MOVED_FROM and IN_MOVED_TO event pairs; a
periodic check detects stale renames where the matching IN_MOVED_TO
never arrived, forcing a resync.
New directory creation triggers recursive watch registration to ensure
all subdirectories are monitored. The IN_MASK_CREATE flag is used
where available to prevent modifying existing watches, with a fallback
for older kernels. When IN_MASK_CREATE is available and
inotify_add_watch returns EEXIST, it means another thread or recursive
scan has already registered the watch, so it is safe to ignore.
Remote filesystem detection uses statfs() to identify network-mounted
filesystems (NFS, CIFS, SMB, FUSE, etc.) via their magic numbers.
Mount point information is read from /proc/mounts and matched against
the statfs f_fsid to get accurate, human-readable filesystem type names
for logging. When the .git directory is on a remote filesystem, the
IPC socket falls back to $HOME or a user-configured directory via the
fsmonitor.socketDir setting.

When a server advertises promisor remotes and the client accepts some
of them, those remotes carry the server's intent: 'fetch missing
objects preferably from here', and the client agrees with that for the
remotes it accepts.
However promisor_remote_get_direct() actually iterates over all
promisor remotes in list order, which is the order they appear in the
config files (except perhaps for the one appearing in the
`extensions.partialClone` config variable which is tried last).
This means an existing, but not accepted, promisor remote, could be
tried before the accepted ones, which does not reflect the intent of
the agreement between client and server.
If the client doesn't care about what the server suggests, it should
accept nothing and rely on its remotes as they are already configured.
To better reflect the agreement between client and server, let's make
promisor_remote_get_direct() try the accepted promisor remotes before
the non-accepted ones.
Concretely, let's extract a try_promisor_remotes() helper and call it
twice from promisor_remote_get_direct():
- first with an `accepted_only=true` argument to try only the accepted
remotes,
- then with `accepted_only=false` to fall back to any remaining remote.
Ensuring that accepted remotes are preferred will be even more
important if in the future a mechanism is developed to allow the
client to auto-configure remotes that the server advertises. This will
in particular avoid fetching from the server (which is already
configured as a promisor remote) before trying the auto-configured
remotes, as these new remotes would likely appear at the end of the
config file, and as the server might not appear in the
`extensions.partialClone` config variable.

When a repack involving promisor packfiles happens, the new ".promisor"
file is created empty, losing all the debug info that might be present
inside the ".promisor" files before the repack.
Use the "copy_promisor_content()" function created previously to preserve
the contents of all ".promisor" files inside the first ".promisor" file
created by the repack.
For geometric repacking, we have to create a `strset` that contains the
basenames of all excluded packs. For "normal" repacking this is not
necessary, since there should be no excluded packs.
Also, update the documentation accordingly.

Let’s change the phrasing around the `linkgit` while we’re visiting this
file (see previous commit[1]).
We use the section syntax to refer to man pages, so writing “man page”
next to it is a bit redundant. We can be more concise and just lean on
the preposition “in”.
And in order to avoid this double “git”:
see `git config list` in git-config(1) ...
We can rephrase to the subcommand, which is a typical pattern (config or
option followed by “in git-command(1)”).

Allow -1 as a value for hook.jobs, hook.<event>.jobs, and the -j
CLI flag to mean "use as many jobs as there are CPU cores", matching
the convention used by fetch.parallel and other Git subsystems.
The value is resolved to online_cpus() at parse time so the rest
of the code always works with a positive resolved count.
Other non-positive values (0, -2, etc) are rejected with a warning
(config) or die (CLI).

Add a hook.<event>.enabled config key that disables all hooks for
a given event, when set to false, acting as a high-level switch
above the existing per-hook hook.<friendly-name>.enabled.
Event-disabled hooks are shown in "git hook list" with an
"event-disabled" tab-separated prefix before the name:
$ git hook list test-hook
event-disabled hook-1
event-disabled hook-2
With --show-scope:
$ git hook list --show-scope test-hook
local event-disabled hook-1
When a hook is both per-hook disabled and event-disabled, only
"event-disabled" is shown: the event-level switch is the more
relevant piece of information, and the per-hook "disabled" status
will surface once the event is re-enabled.
Using an event name as a friendly-name (e.g. hook.<event>.enabled)
can cause ambiguity, so a fatal error is issued when using a known
event name and a warning is issued for unknown event name, since
a collision cannot be detected with certainty for unknown events.
