2021-08-19xfs: convert remaining mount flags to state flagsDave Chinner1-2/+2
The remaining mount flags kept in m_flags are actually runtime state flags. These change dynamically, so they really should be updated atomically so we don't potentially lose an update due to racing modifications. Convert these remaining flags to be stored in m_opstate and use atomic bitops to set and clear the flags. This also adds a couple of simple wrappers for common state checks - read only and shutdown.

2018-06-06xfs: push corruption -> ESTALE conversion to xfs_nfs_get_inode()Dave Chinner1-3/+12
In xfs_imap_to_bp(), we convert a -EFSCORRUPTED error to -EINVAL if we are doing an untrusted lookup. This is done because we need failed filehandle lookups to report -ESTALE to the caller, and it does this by converting -EINVAL and -ENOENT errors to -ESTALE. The squashing of EFSCORRUPTED in imap_to_bp makes it impossible for for xfs_iget(UNTRUSTED) callers to determine the difference between "inode does not exist" and "corruption detected during lookup". We realy need that distinction in places calling xfS_iget(UNTRUSTED), so move the filehandle error case handling all the way out to xfs_nfs_get_inode() where it is needed.

2013-10-23xfs: decouple inode and bmap btree header filesDave Chinner1-1/+1

Move all the btree format definitions from xfs_btree.h, xfs_bmap_btree.h, xfs_alloc_btree.h and xfs_ialloc_btree.h to xfs_format.h to continue the process of centralising the on-disk format definitions. With this done, the xfs inode definitions are no longer dependent on btree header files.

xfs_trans.h has a dependency on xfs_log.h for a couple of structures. Most code that does transactions doesn't need to know anything about the log, but this dependency means that they have to include xfs_log.h. Decouple the xfs_trans.h and xfs_log.h header files and clean up the includes to be in dependency order. In doing this, remove the direct include of xfs_trans_reserve.h from xfs_trans.h so that we remove the dependency between xfs_trans.h and xfs_mount.h. Hence the xfs_trans.h include can be moved to the indicate the actual dependencies other header files have on it.

Now we have xfs_inode.c for holding kernel-only XFS inode operations, move all the inode operations from xfs_vnodeops.c to this new file as it holds another set of kernel-only inode operations. The name of this file traces back to the days of Irix and it's vnodes which we don't have anymore. Essentially this move consolidates the inode locking functions and a bunch of XFS inode operations into the one file. Eventually the high level functions will be merged into the VFS interface functions in xfs_iops.c. This leaves only internal preallocation, EOF block manipulation and hole punching functions in vnodeops.c.
