fs: remove do_sys_truncate

2026-03-23T11:41:58+00:00

do_sys_truncate ist only used to implement ksys_truncate and the native truncate syscalls. Merge do_sys_truncate into ksys_truncate and return int from it as it only returns 0 or negative errnos.

fs: pass on FTRUNCATE_* flags to do_truncate

2026-03-23T11:41:57+00:00

Pass the flags one level down to replace the somewhat confusing small argument, and clean up do_truncate as a result. Signed-off-by: Christoph Hellwig Link: https://patch.msgid.link/20260323070205.2939118-3-hch@lst.de Reviewed-by: Jan Kara Signed-off-by: Christian Brauner

fs: fix archiecture-specific compat_ftruncate64

2026-03-23T11:41:57+00:00

The "small" argument to do_sys_ftruncate indicates if > 32-bit size should be reject, but all the arch-specific compat ftruncate64 implementations get this wrong. Merge do_sys_ftruncate and ksys_ftruncate, replace the integer as boolean small flag with a descriptive one about LFS semantics, and use it correctly in the architecture-specific ftruncate64 implementations.

Note that failures from filename_lookup() are final - ESTALE returned by it means that retry had been done by filename_lookup() and it failed there. Signed-off-by: Al Viro

simplify the callers of file_open_name()

2026-01-13T20:18:08+00:00

It accepts ERR_PTR() for name and does the right thing in that case. That allows to simplify the logics in callers, making them trivial to switch to CLASS(filename). Signed-off-by: Al Viro
