Of course, when it is mounted R/O, it\ndoes not allocate write-buffers as well.\n\nThis optimization is nice but it leads to subtle problems and complications\nin recovery, which I can reproduce using the integck test. The symptoms are\nthat after a power cut the file-system cannot be mounted if we first mount\nit R/O, and then re-mount R/W - \u0027ubifs_rcvry_gc_commit()\u0027 prints:\n\nUBIFS error (pid 34456): could not find an empty LEB\n\nAnalysis of the problem.\n\nWhen mounting R/W, the reply process sets journal heads to buds [1], but\nwhen mounting R/O - it does not do this, because the write-buffers are not\nallocated. So \u0027ubifs_rcvry_gc_commit()\u0027 works completely differently for the\nsame file-system but for the following 2 cases:\n\n1. mounting R/W after a power cut and recover\n2. mounting R/O after a power cut, re-mounting R/W and run deferred recovery\n\nIn the former case, we have journal heads seeked to the a bud, in the latter\ncase, they are non-seeked (wbuf-\u003elnum \u003d\u003d -1). So in the latter case we do not\ntry to recover the GC LEB by garbage-collecting to the GC head, but we just\ntry to find an empty LEB, and there may be no empty LEBs, so we just fail.\nOn the other hand, in the former case (mount R/W), we are able to make a GC LEB\n(@c-\u003egc_lnum) by garbage-collecting.\n\nThus, let\u0027s remove this small nice optimization and always allocate\nwrite-buffers. This should not make too big difference - we have only 3\nof them, each of max. write unit size, which is usually 2KiB. So this is\nabout 6KiB of RAM for the typical case, and only when mounted R/O.\n\n[1]: Note, currently the replay process is setting (seeking) the journal heads\nto _some_ buds, not necessarily to the buds which had been the journal heads\nbefore the power cut happened.

The inode must be consulted for\n permissions when walking, so an RCU inode reference is a must.\n- sb_inode_list_lock to be moved inside i_lock because sb list walkers who want\n to take i_lock no longer need to take sb_inode_list_lock to walk the list in\n the first place. This will simplify and optimize locking.\n- Could remove some nested trylock loops in dcache code\n- Could potentially simplify things a bit in VM land. Do not need to take the\n page lock to follow page-\u003emapping.\n\nThe downsides of this is the performance cost of using RCU. In a simple\ncreat/unlink microbenchmark, performance drops by about 10% due to inability to\nreuse cache-hot slab objects. As iterations increase and RCU freeing starts\nkicking over, this increases to about 20%.\n\nIn cases where inode lifetimes are longer (ie. many inodes may be allocated\nduring the average life span of a single inode), a lot of this cache reuse is\nnot applicable, so the regression caused by this patch is smaller.\n\nThe cache-hot regression could largely be avoided by using SLAB_DESTROY_BY_RCU,\nhowever this adds some complexity to list walking and store-free path walking,\nso I prefer to implement this at a later date, if it is shown to be a win in\nreal situations.

Indeed, we set this to 1 if we switch to\nR/O mode due to an error, and then we test it in many places to\nmake sure that we stop writing as soon as the error happens.\n\nBut this is very unclean. One consequence of this, for example, is\nthat in \u0027ubifs_remount_fs()\u0027 we use \u0027c-\u003ero_media\u0027 to check whether\nwe are in R/O mode because on an error, and we print a message\nin this case.

It also changes all\n\"if (c-\u003ero_media)\" checks to \"if (c-\u003ero_error)\" checks, because\nthis is what the checks actually mean.
