filelock: add FL_RECLAIM to show_fl_flags() macro

2025-10-15T09:59:53+00:00

[ Upstream commit c593b9d6c446510684da400833f9d632651942f0 ] Show the FL_RECLAIM flag symbolically in tracepoints.

filelock: split leases out of struct file_lock

2024-02-05T12:11:44+00:00

Add a new struct file_lease and move the lease-specific fields from struct file_lock to it. Convert the appropriate API calls to take struct file_lease instead, and convert the callers to use them. There is zero overlap between the lock manager operations for file locks and the ones for file leases, so split the lease-related operations off into a new lease_manager_operations struct.

filelock: convert fl_blocker to file_lock_core

2024-02-05T12:11:40+00:00

Both locks and leases deal with fl_blocker. Switch the fl_blocker pointer in struct file_lock_core to point to the file_lock_core of the blocker instead of a file_lock structure.

filelock: have fs/locks.c deal with file_lock_core directly

2024-02-05T12:11:38+00:00

Convert fs/locks.c to access fl_core fields direcly rather than using the backward-compatibility macros. Most of this was done with coccinelle, with a few by-hand fixups.

filelock: rename some fields in tracepoints

2024-02-02T11:09:04+00:00

In later patches we're going to introduce some macros with names that clash with fields here. To prevent problems building, just rename the fields in the trace entry structures.

locks: revise generic_add_lease tracepoint

2019-07-22T10:54:41+00:00

Now that check_conflicting_open uses inode->i_readcount instead of the dentry->d_count to detect opens for read, revise the tracepoint to display that value instead. Also, fl is never NULL, so no need to check for that in the fast assign section. Cc: Amir Goldstein Reported-by: Al Viro Signed-off-by: Jeff Layton

fs/locks: rename some lists and pointers.

2018-11-30T16:26:12+00:00

struct file lock contains an 'fl_next' pointer which is used to point to the lock that this request is blocked waiting for. So rename it to fl_blocker. The fl_blocked list_head in an active lock is the head of a list of blocked requests. In a request it is a node in that list. These are two distinct uses, so replace with two list_heads with different names. fl_blocked_requests is the head of a list of blocked requests fl_blocked_member is a node in a member of that list. The two different list_heads are never used at the same time, but that will change in a future patch. Note that a tracepoint is changed to report fl_blocker instead of fl_next.
