Merge patch series "fix architecture-specific compat_ftruncate64 implementations"
Christoph Hellwig <hch@lst.de> says:
This series fixes a really old bug found by code inspection, where the
architecture-specific 32-bit compat ftruncate64 implementations enforce
the non-LFS file size limit unless opened with O_LARGEFILE.
* patches from https://patch.msgid.link/20260323070205.2939118-1-hch@lst.de:
fs: remove do_sys_truncate
fs: pass on FTRUNCATE_* flags to do_truncate
fs: fix archiecture-specific compat_ftruncate64
