CVE-2026-90318

fat: release buffer head after rebuilding parent

In the Linux kernel, the following vulnerability has been resolved:

fat: release buffer head after rebuilding parent

fat_scan_logstart() leaves the matching directory entry's buffer head in
sinfo.bh for the caller to release, just like fat_scan().

fat_rebuild_parent() uses the directory entry to rebuild the parent inode
for the nostale_ro NFS export path, but does not release sinfo.bh after a
successful scan.  Release it once fat_build_inode() has consumed the
directory entry data.
