2017-01-14locking/atomic, kref: Add kref_read()Peter Zijlstra1-1/+1
Since we need to change the implementation, stop exposing internals. Provide kref_read() to read the current reference count; typically used for debug messages. Kills two anti-patterns: atomic_read(&kref->refcount) kref->refcount.counter Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Paul E.

2012-08-12exofs: check for allocation failure in uri_store()Alexey Khoroshilov1-1/+6
There is no memory allocation failure check in uri_store(). That can lead to NULL pointer dereference. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by: Alexey Khoroshilov <khoroshilov@ispras.ru> Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>

2012-05-21exofs: Add SYSFS info for autologin/pNFS exportSachin Bhamare1-0/+200
Introduce sysfs infrastructure for exofs cluster filesystem. Each OSD target shows up as below in the sysfs hierarchy: /sys/fs/exofs/<osdname>_<partition_id>/devX Where <osdname>_<partition_id> is the unique identification of a Superblock. Where devX: 0 <= X < device_table_size. They are ordered in device-table order as specified to the mkfs.exofs command Each OSD device devX has following attributes : osdname - ReadOnly systemid - ReadOnly uri - Read/Write It is up to user-mode to update devX/uri for support of autologin. These sysfs information are used both for autologin as well as support for exporting exofs via a pNFSD server in user-mode.
