linux.git/fs/reiserfs, branch v2.6.26 Linux kernel source tree reiserfs: discard prealloc in reiserfs_delete_inode 2008-07-08T19:39:31+00:00 Jeff Mahoney jeffm@suse.com 2008-07-08T18:37:06+00:00 eb35c218d83ec0780d9db869310f2e333f628702 With the removal of struct file from the xattr code, reiserfs_file_release() isn't used anymore, so the prealloc isn't discarded. This causes hangs later down the line. This patch adds it to reiserfs_delete_inode. In most cases it will be a no-op due to it already having been called, but will avoid hangs with xattrs.

reiserfs: unpack tails on quota files 2008-04-28T15:58:46+00:00 Jan Kara jack@suse.cz 2008-04-28T09:16:23+00:00 d5dee5c395062a55236318ac4eec1f4ebb9de6db Quota files cannot have tails because quota_write and quota_read functions do not support them. So far when quota files did have tail, we just refused to turn quotas on it. Sadly this check has been wrong and so there are now plenty installations where quota files don't have NOTAIL flag set and so now after fixing the check, they suddently fail to turn quotas on. Since it's easy to unpack the tail from kernel, do this from reiserfs_quota_on() which solves the problem and is generally nicer to users anyway.
