Subject: s_fs_info and ->kill_sb revisited
Date: Tue, 8 Aug 2023 09:15:47 -0700 [thread overview]
Message-ID: <20230808161600.1099516-1-hch@lst.de> (raw)
Hi all,
this series is against the VFS vfs.super branch does two slightly
related things:
- move closing of the external devices in ext4 and xfs from ->put_super
into ->kill_sb so that this isn't done under s_umount which creates
lock ordere reversal
- move freeing the private dta in s_fs_info into ->kill_sb for file systems
that pass it in through the fs_context, as otherwise we could leak it
before fill_super is called (this is something new on the vfs.super
branch because of the changed place where blkdev_get is called)
Diffstat:
exfat/exfat_fs.h | 2 -

ntfs3/super.c | 33 ++++++++++------------
